The chambers I8 and I9 constitute ascending and descending portions of the smoke conducting passage or duct I4 and are disposed transversely or angularly relative to the longitudinal run of said duct. The chambers I8 and I9 are open at the top 20 of the extension I I and serve as means for receiving suitable elements for absorbing the deleterious or obnoxious liquid constituents in the smoke. The relatively flattened extension II thus provided may serve, if so desired, as a grip for holding the pipe, and the surfaces thereof may serve for the attachment of monograms, emblems or other ornamental devices by means extending through the portion 2I of the extension intermediate said chambers I8 and IS.

The chambers I8 and I9 are provided with tubular metallic linings 22 and 23 coextensive with the length thereof and which project at the lower ends 24 and 25 thereof into the bore I4 to form barriers between the inlet portions I l of the bore and the discharge portions I I thereof. The tube or lining 22 has an inlet opening 26 therein aligned with the bore portion I4 for the passage of the smoke into the chambers I8 and I9, and the tube 23 has an outlet opening 21 therein aligned with the bore portion I4 for the discharge of smoke into the bit H. The metallic linings 22 and 23 serve to prevent the absorption of the liquids by the walls of the chambers I8 and I9, and to provide interior surfaces which may be readily cleaned.

Cylindrical filtering or absorbing elements or cartridges 28 are disposed within the chambers I8 and I9 to abstract from the smoke any obnoxious or deleterious matter carried thereby. These elements preferably comprise a body 29 of gauze, fibre or other suitable liquid absorbing material, and an impervious open-ended enclosure 30 of a paper, cellophane or similar material for retaining the elements to shape and permitting the same to be handled with cleanliness. The elements or cartridges 28 are preferably carried or held by a separate member 3| of tubular formation adapted to be inserted into the chambers I8 and I9 at the open upper ends 20 thereof to close said open ends and form a bridging connection between the chambers I8 and I9 to establish communication therebetween. The tubular member or holder 2| is preferably substantially of U-shape form, and includes the transverse portion 32 and the angularly related tubular, open-ended leg portions 33 of a length slightly less than that of the chambers I8 and I9 and of corresponding shape to closely fit the chambers. The cylindrical absorbing cartridges or elements 28 are inserted into and closely fit within the open ends of the portions 33 in position to project a short distance beyond the ends thereof, as indicated at 34 to provide portions adapted to be gripped in removing the cartridge from the holder. Entry of the cartridges or elements 28 into the transverse portion 32 of the carrier or holder 3| is prevented by an open spacer 35, illustrated as being composed of a coiled wire or spring located within and substantially filling the space within the portion 33. The cartridges 28 and the legs 33 are relatively dimensioned in length so that the lower ends 34 of the cartridges will not project over the openings 26 and 21 in the sleeves or linings 22 and 23 thereby to block or close the same. The structure or arrangement thus provided leaves the ends of the laterally enclosed cartridges 28 fully open for the free passage of the smoke therethrough, and prevents obstruction of the smoke passage by the impervious walls of the cartridges particularly at the entrance and discharge ends I4 and I4 and at the bridging member 3|.

If so desired, the pipe may be provided with means 36 for closing the open end of the bowl II] to prevent the escape of sparks and ash when the pipe is in use. The bowl closing means 36 is preferably made readily attachable to the pipe, and detachable therefrom when the use of the device is not desired. For this purpose, the closing means 36 comprises a bifurcated attaching member 37 adapted to straddle the relatively narrow extension portion II of the pipe adjacent the bowl with the edge portions 38 of the slot 39 engaged in the vertical grooves or slots 40 on the pipe at opposite sides thereof located substantially at the juncture of the portion I I with the bowl I0. The member 31 frictionally interlocks with the grooves 40, and is thus secured to the pipe with the bridging portion M of the attachment located substantially on a plane with the top of the bowl III. The top of the bowl I0 is closed by means of a perforated cover plate 42 hinged or pivoted at 43 to the upper end of the member 31. After the cover device 36 is applied to the pipe the cover plate 42 may be readily swung down against the top of the bowl and secured in closed position by the catch 43 carried thereby. Upon the detachment or removal of the device 38 from the pipe, the parts 31 and 42 may be folded together to render the same compact. The device 36 when folded may be readily carried about in the pocket, and readily applied to and detached from the pipe, as desired.

In operation, the cartridges 28 may be readily inserted into the carrier or holder 3| in position as shown in Fig. 5. The member 3| may then be readily inserted into the metal lined socket chambers I8 and I9 to complete the smoke conducting passage and position the cartridges therein. The smoke in being drawn through the pipe traverses the succession of filtering or absorbing elements which remove the distillates, oils and other liquids from the smoke, thereby freeing the smoke from undesirable constituents for delivery in a dry, clean state to the mouth. When the absorbing elements become saturated or otherwise unfit for use the member 3I may be readily withdrawn and the cartridges therein replaced without requiring disconnection or separation of other portions of the pipe, such as the bit or mouth piece. The pipe is also fully operative for smoking with either or both of the absorbent elements omitted.

The metallic linings or tubular members 22 and 23 provide surfaces for the interior of the sockets capable of being readily cleaned and prevent absorption of the fluids by the walls of the chambers, thereby rendering the pipe less odorous. A good sliding contact between the sockets I8 and I9 and the cooperating holder Si is thus provided and maintained. lower ends of said tubular linings 22 and 23 serve as means for blocking the longitudinal bore I4 to prevent the direct passage of the smoke therethrough.

By my invention I am able to obtain a substantially dry smoke without impairing the normal operation of the pipe or unduly complicating the structure thereof. By the provision of the plurality of cartridge receiving chambers formed in In the present invention the.

the extension I l, as described, the absorbent path is substantially extended or lengthened, without unduly increasing the size of the pipe, and thus insure full withdrawal of the deleterious or obnoxious fluids from the smoke.

Having thus described my said invention what I claim and desire to secure by Letters Patent is:

1. A smoking pipe comprising a bowl having an extended wall portion, a smoke conducting passage in said extended wall portion including transverse passage portions open at the outer ends thereof, and a tubular bridging member including depending legs extending into said passage portions and an intermediate portion, an open spacer within said intermediate portion, and absorbent elements within said legs engaging said spacer at the inner ends thereof.

2. A smoking pipe comprising a bowl having an extended wall portion, a stem, a smoke conducting passage including a portion in said stem and ascending and descending portions in said extended wall portion open at the outer ends to provide sockets, a tubular bridging member including an intermediate portion and depending end portions removably disposed in said sockets for communicatively connecting said ascending and descending portions, said end portions serving to removably receive absorbent elements, and means for maintaining the inner ends of the absorbent elements spaced from the opposing wall of the intermediate portion.

3. A smoking pipe comprising a bowl having an extended wall portion, a stem, a smoke conducting passage including a longitudinal portion in said stem and ascending and descending portions in said extended wall portion open at the outer ends, a tubular bridging member having an intermediate portion and depending end portions of a length shorter than that of said ascending and descending portions and removably disposed therein to establish communication therebetween, absorbent elements having impervious openended casings removably received within said depending end portions and projecting beyond the free ends of said depending end portions and into the ascending and descending portions of said smoke conducting passage, and means for maintaining the absorbent elements at the inner ends thereof spaced from the opposing wall of the intermediate portion and in position allowing the free passage of the products of combustion therethrough.
